RECOMMENDED FUELS

Please note

 If you live in a UK Smoke Control Area 

you must only burn approved smokeless fuels. The  
following fuels are approved by Olymberyl for use in 
the HF443-B Olymberyl Boiler stove:
• 

Wood Logs

 

Only ever use dried, fully seasoned 

chopped wood logs with a moisture content of less 
than 20%. 

Wood which is well seasoned makes a distinctive 
‘clack’ rather than a dull ‘thud’ when knocked  
together. It will also feel much lighter than an  
unseasoned log. Other indicators include bark peeling 
away and cracking and splitting around the outside.
Ideally wood should be seasoned outdoors for  
between 18 to 24 months – the harder the wood 
then the longer the seasoning. It should be stacked 
off the ground with plenty of space between the logs 
to allow air movement and with the top covered to 
keep rain and snow out. It is said that seasoned wood 
will provide approximately 50% more heat output 
than the equivalent unseasoned log.
Most types of hardwood, for instance Ash (generally 
regarded as the best), Birch, Beech, Oak and Elm can 
be used. However, avoid woods with a high resin  
content. As a rule of thumb, the heavier the wood, 
then the greater the heat output and the longer burn 
time – the time between refills. All of this is providing 
that it is fully seasoned wood.

Never use wet or unseasoned (green) wood as this will 
cause nuisance smoke and a very disappointing fire. 

 

Its use could quickly result in the build up of soot and 
creosote – in a matter of weeks sometimes, which  
because of the higher temperatures of stove flue 
gases, could easily cause a flue or chimney fire. In  
addition, burning wet wood creates other  
environmental problems, a less efficient fuel economy 
and can eventually clog your flue system and cowl. It 
will also reduce the effectiveness of the stove’s  
Airwash system thus causing staining and blackening 
of the glass. 
Wet or unseasoned would produces the following 
poor performance:
• Hard to light fires
• Fires that are difficult to keep going or to keep 
   burning well
• Smoky fires with fewer flames which are also of a 
   dull orange colour
• Increased dense grey / blue smoke from the chimney
• Shorter burn times
• Low heat output
• Dirty glass and firebricks
• Excessive and rapid creosote build-up in the flue 
   system and chimney

• Unpleasant smoky smells both inside and sometimes 
   outside the house 
In the event of a problem with your stove – always 
check your choice of fuel first!
Manufactured or finished wood products, such as 
plywood and chipboard, must also be strictly avoided  
because of the high chemical adhesive content used 
in their production which will also leave harmful, 
potentially corrosive, residue inside the stove and flue 
system.

DEFRA funded National Energy Foundation website

• Peat or ‘Turf’ 

Peat is an excellent cost-effective fuel 

alternative and provides a similar calorific heat output 
to wood. It’s also clean and easy to handle with low 
atmospheric emissions. However, you must ensure 
that the peat is kept thoroughly dry as it absorbs and 
retains unwanted moisture very easily. 
Peat has traditionally been used as a heating fuel in 
both Scotland and Ireland and you can find out more 
by visiting these suppliers’ useful websites – �www.
peatheat.co.uk (Scotland) and www.bnm.ie/fuels 
(Ireland). 
Should you prefer to burn peat we would strongly  
recommend using 904L grade flexible liner to line your 
chimney as this is more resistant to the acids in peat.

• Multi Fuels (Other than Wood or Peat)

 If you 

cannot burn wood then we recommend burning a 
smokeless alternative, such as smokeless ovals, as this 
is better for the stove and flue system as well as the 
environment. Your stove is also approved to burn coal 
– however, we do not recommend prolonged use of 
bituminous house coal because of the excessive soot 
it produces. There are many different brands of high 
quality smokeless coal ovals available in the UK and 
Ireland. The most popular include Phurnacite, Taybrite, 
Ancit and Homefire. 
Your local fuel merchant will be able to advise you on 
the best types of coals suitable for multi fuel stoves, 
as well as natural mineral fuel alternatives such as 
anthracites which burn cleanly. The following fuel 
merchant’s website also has good descriptions of the 
comparative benefits that the brands listed above 
have to offer –

website

PROHIBITED FUELS

Never use your stove like an incinerator. Burning  
prohibited ‘fuels’ in a Smoke Control Area is illegal.

Burning the following materials could also damage 
your stove and flue system, rendering the product 
warranties on the stove and flue system components 
void.
